Patent Images
1. An acromioclavicular brace comprising:
- means attachable to the torso of an injured person for providing a first anchoring site for reduction strap assembly means and for providing an adductive force to the upper arm corresponding to an injured shoulder joint;
mounting means for providing a second anchoring site for the reduction strap assemblies at a position disposed adjacent the ulna of the affected arm;
a resilient force-focusing member adapted to be positioned superior to the distal end of the affected clavicle;
semblant pulley means for providing mechanical advantage, said semblant pulley means including ring means having at least one straight, elongate portion; and
at least one force multiplying reduction strap assembly means including two or more ambient pulley means and flexible connecting means adapted for coursing through said semblant pulley means and attaching to said first means mentioned, said second means mentioned, and said force focusing member whereby an adductive force is applied to said second named means and a multiplied reductive force is applied through the force focusing member to the affected distal clavicle.

Abstract
A brace is provided for treatment of acromioclavicular dislocations. The brace includes a bandage member or body swathe which encircles the thorax and the involved upper arm, a resilient force focusing member or shoulder pad located atop the distal end of the clavicle, and reduction straps disposed between said members which operate through semblant pulleys to afford immobilization of the acromion and a multiplied reductive force on the dislocated clavicle whereby to hold the acromioclavicular joint in location.

2. An acromioclavicular brace comprising:
- means attachable to the torso of an injured person for providing a first anchoring site for reduction strap assembly means and for providing an adductive force to the upper arm corresponding to an injured shoulder joint;
mounting means for providing a second anchoring site for the reduction strap assemblies at a position disposed adjacent the ulna of the affected arm;
a resilient force-focusing member adapted to be positioned superior to the distal end of the affected clavicle;
semblant pulley means for providing mechanical advantage, said semblant pulley means including a ring means having at least one straight, elongate portion; and
reduction strap assembly means including a first semblant pulley means fixed ventrally to said first means mentioned, ventral strap means fixed to an anterior edge portion of said force-focusing member, said ventral strap means coursing inferiorly through said first semblant pulley means and returning superiorly through a second semblant pulley means fixed to an anterior edge portion of said force-focusing member and continuing inferiorly and attaching to the distal end of said second named means, whereby a multiplied reductive force affected by the weight of the involved arm is applied ventrally through the force-focusing member to the distal end of the affected clavicle, said reduction strap assembly means further including a first semblant pulley affixed dorsally to said first mentioned means, a second semblant pulley fixed to a posterior edge portion of said force-focusing member, dorsal strap means fixed to a posterior edge portion of said force-focusing means, said dorsal strap means coursing inferiorly through said first semblant pulley and returning superiorly through said second semblant pulley means and returning inferiorly and medially and continuing dorso-ventrally and attaching to said second named means, whereby an adductive force is applied to said second named means and a multiplied reductive force is applied through the force-focusing member to the distal end of the affected clavicle.
- means attachable to the torso of an injured person for providing a first anchoring site for reduction strap assembly means and for providing an adductive force to the upper arm corresponding to an injured shoulder joint;
